New mother Chelsea Clinton helped launch the first report on the “State of the World’s Fathers” on Tuesday which says major inequalities persist between parents with women spending between two and 10 times longer than men caring for children.

The report said there is no country in the world where men and boys share unpaid domestic and child care work equally with women and girls — despite the fact that women today comprise 40 percent of the global workforce and 50 per cent of the world’s food producers.

Clinton, vice chair of the Bill, Hillary and Chelsea Clinton Foundation which helped support the report, told a UN event launching it that changes in mindsets, policies and practices are needed to get fathers to play a bigger role.

“I hadn’t understood that one of the great joys of becoming a mother would be watching my husband become a father,” said Clinton, whose daughter Charlotte is now eight-months-old. “And I am so grateful for his dedication and his support and his love, and the investments that he makes in our daughter every single day. … His commitment to her is very much in both his and her best interest.”

The report said about 80 per cent of the world’s men and boys will become fathers in their lifetime, and virtually all men will have some connection to children in care giving relationships. It also said that between 61 percent and 77 percent of fathers say they would work less if they could spend more time with their children, but only 92 countries offer paternity leave and for half it’s less than three weeks.

The report was produced by MenCare, a global campaign to promote men and boys as equal caregivers, and was supported by several UN agencies and many non-governmental organizations and foundations. It brings together international research findings, with global examples.

Kate Gilmore, deputy executive director of the U.N. population agency UNFPA, called the report “historic.”

“Men who have close relationships with children live longer, they have fewer mental and physical health problems, they’re less likely to be dependent on drugs, and more productive at work,” she said.

UN Women Executive Director Phumzile Mlambo-Ngcuka said in the preface that the report “fills a much-needed gap.”

“The promotion of gender equality in the household, particularly with regard to parenting, is a key step in laying the foundation for gender equality in society more broadly,” she said.
